Haze pollution in winter and summer in Zibo, a heavily industrialized city neighboring the Jin-Jin-Ji area of China: source, formation, and implications

Abstract

14Continuous field observations of haze pollution were conducted in winter and summer during 15 2015 in Zibo, a highly industrialized city in the North China Plain that is adjacent to the Jing-Jin- reactions between HNO3 and NH3 in the gas phase, followed by partitioning into the particle 31 phase. The RH, NO2, and "Excess NH4 + " were the main influencing factors for nitrate in winter, 32 whereas "Excess NH4 + ", RH, and temperature were the key factors in summer. Zibo, one of the most polluted cities in north China, and its adjacent areas should be taken into 37 Atmos. Chem. Phys. Discuss., https://doi
